AimContribution to the authorship, including that for case reports, should be appropriately evaluated. I have noticed a scarcity of case reports with clinic doctors listed as coauthors, prompting this investigation. I sought to offer suggestions on the possible reasons for this trend.MethodsI checked case reports published in the Journal of Obstetrics and Gynaecology Research, the Journal of Medical Case Reports, and the BMJ Case Reports. I identified case reports listing a clinic doctor as a coauthor. I consulted eight professors at Jichi Medical University to ascertain whether case reports from their departments included clinic doctors as coauthors and, if not, the reasons.ResultsAmong 65 case reports from Japanese institutes published in the Journal of Obstetrics and Gynaecology Research, only one paper lists a clinic doctor as a coauthor. Of 100 and 50 papers published in the Journal of Medical Case Reports and BMJ Case Reports, respectively, none listed a clinic doctor as a coauthor. Six out of eight professors admitted to never considering the idea of including clinic doctors as coauthors.ConclusionsThe scarcity of case reports with clinic doctors as coauthors extends beyond Japanese obstetrics and gynecology, encompassing various specialties worldwide. Center doctors do not think of the idea that a clinic doctor should be a coauthor. A clinic doctor who transferred the patient should be considered as a candidate coauthor depending on his/her scientific contribution. Such an approach could foster an environment encouraging doctors to contribute to academic writing, regardless of their workplace.

Intracranial hypotension-associated cerebral swelling following cranioplasty: Report of two cases

et al. 2017

View full text Add to dashboard Cite

Cranioplasty is a comparatively simple neurosurgical procedure, and fatal complications are rare. This report describes two cases of critical brain swelling after otherwise uneventful cranioplasty. Both cases had subarachnoid hemorrhage and extremely similar clinical courses. They underwent decompressive craniotomy and clipping in the acute phase and had cranioplasty in the chronic phase, resulting in serious cerebral swelling and death. Deep venous sinus thrombosis was revealed in the autopsy for one case. Although no venous occlusion was identified in the other case, radiological findings suggested venous congestion. In both cases, intraoperative cerebrospinal fluid leakage was massive and was prolonged by a drain; therefore, we hypothesized that intracranial hypotension (IH) caused stagnation of venous flow. Neurosurgeons should be aware that fatal venous congestion induced by IH may occur after cranioplasty. To avoid this, tight dural closure should be obtained, and avoidance of the use of subcutaneous drains should be considered.

“…Hypertension, which promotes the occurrence of cerebral venous dysfunction-mediated brain tissue damage, such as venous sinus thrombosis, venous cerebral infarction, venous cerebral hemorrhage, periventricular venous disease, venous neurocytotoxicity, neurodegeneration and demyelination, is one of the primary risk factors of cerebrovascular disease ( 1 – 4 ). Vascular remodeling has been shown to be important for the progression of hypertension-mediated cerebrovascular disease ( 5 ).…”

Caveolin‑1 modulates hypertensive vascular remodeling via regulation of the Notch pathway

Hypertension is one of the critical risk factors of cerebrovascular disease. caveolin-1 (cav-1) has been suggested to be involved in the development of hypertension; however, the underlying mechanism remains largely unknown. Therefore, the present study aimed to investigate the mechanism underlying cav-1 in hypertension. in the present study, the hypertension model was induced by infusion of angiotensin ii (ang-ii) in rats. cell counting Kit-8 assay was used to detect the viability of human umbilical vein endothelial cells (HuVecs). Flow cytometry was used to determine the apoptosis of HuVecs. Transmission electron microscopy was utilized to address the thickness of the vessel walls. reverse transcription-quantitative Pcr, western blotting and immunofluorescence staining were used to assess the mechanism of cav-1/notch1 involved in hypertensive vascular remodeling. in the present study, an ang-ii-induced hypertension model was successfully established in rats. With this model, it was found that the expression levels of cav-1 and notch1 were significantly increased in brain tissues in the hypertension group compared with the sham-operated group. in cultured HuVecs, knockdown of cav-1 regulated ang-ii-induced HuVec viability and apoptosis, and modulated hypertensive vascular remodeling, which was mediated by the notch pathway. The data of the present study demonstrated that the cav-1/notch signaling plays an important role in the regulation of ang-ii-induced hypertension and vascular remodeling.
